I've inherited a couple 4402 Wireless LAN Controllers and am in charge of getting them ship-shape. While I have some general knowledge of wireless, I have not worked with wireless controllers before and have a couple questions I was wondering if anyone could help me with:
1) How can I verify that the primary and secondary controllers are configured for failover without actually performing a test? Both do have AP Failback enabled, but I'm not sure what else to check.
2) They are currently running code 3.2.116.21. Should I stick with 3.2 or plan to move up to 4.X?
Thanks a bunch. I'm slowly working my way through the docs and answers to these would sure speed things up.

Hi Johnny,
Hope things are well with you! The steps required to configure AP Fallback are detailed quite nicely in the attached doc. I would always try to schedule a Maintenance window to test this out rather than not knowing for sure :)

Now, for your second question, it's likely that you will want to upgrade the WLC to a newer version of code. They have gone through 4.0.x,4.1.x and the newest is 4.2.x. So 3.2 is a fair ways behind. Have a look at the WLC Release Notes;

Hi Rob,
Thanks for the input. TAC pointed me to the same doc, and after taking all those steps it finally worked after I erased the config on each AP. Sounds like this might be a bug on the 3.2 Controller code (I haven't looked through all the bugs, but do see there plenty of justify moving up to 4.X)

Hi Johnny,
You are most welcome! Glad to help in some very small way :)
Take care,

Great tip. I had tried to jump up to 4.1 and it gave me an error about the flash memory. This would explain why it failed.
